The bulk of the collection comprises rendered presentation drawings delineated by Todd. Many of the firm's major planning, civic, commercial, and residential projects are represented in the collection including the firm's master plan for the U.S. Capitol. Projects particularly well documented include the Baltimore - Inner Harbor Master Plan and the Nigerian Federal Capitol Master Plan. Neither the plan of the Valleys (Baltimore 1963) nor the Pardisan project (Tehran, Iran 1975) is represented.
